For any construction project to be successfully completed, an effective process, integrating all the individual pecking orders, is needed. This is where the delineation of Interface Points (IPs) comes into the limelight. An Interface Management Protocol (IMP) should be established to plan and coordinate all the IPs for the different packages. As an aspiring PMI Construction Professional (PMI-CP), it is essential for you to understand and implement this in your projects.
Interface Points and Their Importance
Interface Points (IPs) are the junctures where two or more project segments meet. These points should be well-managed since they carry the potential for significant overlays, gaps, and contradictions. They could involve people, procedures, equipment, works coordination or any other facets of a project.
If these interfaces are well-orchestrated, it would ensure effective communication and coordination, improve the quality of work and reduce potential conflicts. This would eventually increase efficiency and lower the project expenditure.
Planning of Interface Points
- Identification of Interfaces: The initial step involves classifying and documenting all the potential Interface Points (IPs). These could be Internal (within the project) or External (within the organization but outside the project).
- Interface Matrix: This matrix could serve as a helpful tool in determining the Interface Points. For example, consider a construction project divided into plumbing, electrical, HVAC and civil work. The interface matrix would reveal the points where these individual segments intersect.
| Plumbing | Electrical | HVAC | Civil | |
|---|---|---|---|---|
| Plumbing | – | X | X | X |
| Electrical | X | – | X | X |
| HVAC | X | X | – | X |
| Civil | X | X | X | – |
Legend: X denotes an interface point.
- Interface Responsibility Matrix: After identifying the IPs, the next step is to distribute the responsibilities. Interface responsibilities should be shared and not transferred, to maintain higher control and accountability.
- Develop Interface Documents: Record all the relevant details (like scope, interface manager, interface timing and duration, constraints and risks) for each IP. For visualization, highlighting the interfaces on the plan layout could also be useful.
Establishing the Interface Management Protocol
The Interface Management Protocol (IMP) provides guidelines for the retrieval, distribution and storage of interface information.
- IMP should lay out clear procedures about who is responsible for what, and when they are liable to the task.
- It should provide a standard method for documenting, communicating and resolving all interface issues.
It’s advisable to implement an Interface Management System (IMS) which can act as a repository for all interface information and activities, enabling easy management and updates.
Example
Consider a construction project involving the building of an eco-friendly building. The primary work packages can be divided into: Solar Panel Installation, Rain-water Harvesting, and Building Construction.
The interfaces would exist where these different packages intersect. For instance, the placement of solar panels would have an interface point with building construction, as it would need coordination with the civil team to ensure structural integrity.
Conclusion
The effective planning and management of the interface points would undoubtedly lead to a smooth operational flow of the project. It mitigates the risks of miscommunication, delays and rework while improving the overall efficiency and quality. Hence, as a PMI-CP candidate, the understanding and ability to manage IP’s is an invaluable asset for your project management career.

Answer: False.
Explanation: The nature of projects often means that interfaces may change, and new ones could come up during the project’s life cycle. Hence, interface point planning is an ongoing activity.
Interface management is the same as:
- A. Risk management
- B. Time management
- C. Stakeholder management
- D. None of the above
Answer: D. None of the above.
Explanation: While it interacts with and includes aspects of risk, time, and stakeholder management, interface management is a discipline in its own right, focusing on coordination between different project elements.
True or False: Interface management is critical in making sure ambiguous areas of the project are not overlooked.

Interview Questions
What is meant by Interface points (IPs) in construction project management?
Interface points (IPs) in construction project management refer to the touchpoints or areas of interaction between different work packages, phases, or tasks within a project.
Why is it important to plan and establish interface points in a construction project?
It’s important because they serve as a critical part in interconnecting different project tasks. It aids in the smooth flow of work, enhances communication, and mitigates risks related to overlapping or misaligned tasks.
How can conflicts between Interface Points (IPs) be managed effectively?
Conflicts can be managed through clear communication, joint risk management, and inclusive decision making involving all stakeholders. Regular update meetings and having a defined conflict resolution strategy also help.
What is the role of a Construction Professional in managing IPs?
The construction professional is responsible for identifying, planning, and managing all interface points. They ensure smooth interaction between different packages to avoid delay, miscommunication or risk.
